The Sun Hydraulics NCFBHEV (NCFBHEV) is a needle valve with a reverse flow check designed for precise flow regulation. This versatile component is fully adjustable, allowing for fine-tuning from fully closed to the maximum orifice diameter. It features an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCFBHEV model is compatible with all 2-port flow control cartridges of the same frame size, ensuring functional interchangeability while accommodating variations in cartridge extension dimensions from the mounting surface. This needle valve operates by regulating flow based on the square root of the pressure differential across its ports due to its non-compensating nature. The balanced adjustment mechanism facilitates easy adjustments even under high pressure conditions, while the sharp-edged orifice design minimizes variations caused by changes in fluid viscosity. The Sun floating style construction reduces the risk of internal binding from excessive torque or machining discrepancies. The NCFBHEV has a capacity of 30 gpm (120 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It exhibits minimal leakage at specified conditions and allows for up to 5.5 counterclockwise turns from fully closed to open. Installation requires specific torque settings for both the valve and locknut, ensuring secure placement and optimal performance. The model weighs approximately 1.30 lb (0.60 kg) and comes with a Viton seal kit option for enhanced durability and reliability in various applications.

Needle valves with reverse-flow check are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1. They are not pressure compensated.
- All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
- Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2.
- A balanced adjustment mechanism allows for easy adjustment even at high pressures.
- The sharp-edged orifice design minimizes flow variations due to viscosity changes.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
